Best Artists/Tracks at Chord Changing

Petty often favors those ringing open major key chords. There are lots of others who bark up that tree, but rather than listing them here (one LONG list), I'd suggest that you might check out Pandora. Create a "Tom Petty" channel and Pandora will seek out similar music. It's far from perfect, but the odds are pretty good that you'll find a lot of what you're after.

BTW, Petty's songwriting is so archetypal in so many ways that I always joke to my wife (a huge Petty fan and a huge Pandora fan) that - no matter who you enter in Pandora - it will eventually end up back at Tom Petty.

Steely Dan, Holdsworth, Ponty, Happy The Man, Prokofiev, Ravel, Chicago, The Mars Volta.

Tom uses sus chords a lot i think, which he then resolves back to the root chord

I don't see anything hard or extraordinary to juggle with sus chords. Typical american guitar

I dont think its about how simple the changes are, or how complicated the progression is or how often it is used.Good music could mean someone using one chord or throwing everything but the kitchen sink in a tune.But I seem to be attracted to good songwriting and well performed pieces ,rather than songs that are more or less a platform for a musician to show everyone how fast he can play,or how many tricks he can do.I would rather listen to Hubert S. with Howling Wolf do Smoke Stack Lightning than,,,,,,,,,well,any number of the so called super players. Some folks can make 3 chords sound so good.Having said this,I also Love Steely Dan,Early Yes,Frank Zappa,Jaco,many busy players.
